MK 38 - 25 mm Machine Gun System
The MK 38 is a 25 mm machine gun system (MGS) installed for ship self-defense to counter Fast Attack Crafts and Fast Inshore Attack Crafts.
The MK 38 MOD 0 25 mm MGS replaced the MK 16 20 mm gun system and was then upgraded to a MK 38 MOD 1 MGS. A total of 387 MK 38 MOD 1 MGSs were procured and deployed in the U.S. Navy and U.S. Coast Guard. In 2003, the CNO directed the Navy to pursue a simple, stabilized, remote controlled, low cost solution for outfitting near-term deployers to counter small boat threats. In response, the Navy began fielding the MK 38 MOD 2 MGS in 2005. Due to the success of the MK 38 MOD 2 MGS, the program scope was expanded in July 2012 to add several ship classes and to develop a modification to the system. This modification is known as the MK 38 MOD 3 MGS, which is a technical refresh of the MK 38 MOD 2 MGS. The first MK 38 MOD 3 MGS is to be fielded in FY17. As of 2018, 341 MK 38 MOD 2 and MOD 3 systems have been delivered. The total number of systems within the Program of Record is 501.
Installed aboard CG, CVN, DDG, LSD, LHD, LHA, LCC, MK VI, PC, OSV, AS and USCG FRC class ships and planned for installation aboard USCG OPC and WMEC class cutters, the MK 38 MGS is a low cost, stabilized self-defense weapon system that dramatically improves ships' self-defense capabilities.
